LH-800B special chelating resin for boron removal by ternary electrolysis

It is a macroporous styrene-divinylbenzene skeleton with coordination

High molecular polymer with amine groups (N-methylglucosamine). N-methylglucosamine is similar to a monosaccharide and can be interacted with boron

Acids form very stable complexes and are inert to other anions, which facilitate interaction with borate ions in water

A stable complex is formed, thereby achieving the removal of borate in aqueous solution.

This group is sensitive to pH value, and the formation of complex ions can only be formed in neutral and alkaline solutions, and the complex ions decompose in acidic solutions.

It is suitable for electrolytic boron removal, boron removal in boron-containing aqueous solutions such as drinking water and irrigation water, and has high adsorption capacity and fast adsorption speed for borate ions. As well as desalination and deboronization of seawater, and regulation of boron content of nuclear reactor.

Resin Use

1. Put a certain amount of nitrate removal resin into the filter according to the quality and water flow speed of the water you need to purify

In the core, in order to prevent water from carrying away the resin particles, please install grids with appropriate pore sizes at both ends of the filter element. For general

When filling resin, the inlet and outlet water pipes and exchange columns should be flushed with pure water first to ensure that there are no impurities inside.

2. Slowly pour the resin into the exchange column, fill the resin to the specified height, and then seal the exchange column with a lid

Change the column.

3. During the resin packing process, it should be ensured that there is no water in the exchange column.

4. Install the filter element filled with filter material into the water purification device, turn on the water inlet switch, and make the water to be purified

The filter material flows at a certain flow rate. The initial outflow water is turbid, which is the air discharge and particle surface residue in the boron removal resin

It is a normal phenomenon that impurities remain and fall off.

5. Use incoming water to quickly clean the resin at a flow rate of 10 ~ 30 BV/h until the effluent water quality is qualified, that is

Accessible for use.

6. The decrease in water flow rate and the increase in pressure drop after long-term use are due to the contaminants in the water on the resin surface and pores

It is caused by adsorption and accumulation, and regular recoil is beneficial to alleviate this phenomenon.

Storage of resin

1. The resin should be sealed and stored indoors in a cool place, avoiding sunlight, and away from boilers, heaters, etc.

Thermal device to avoid resin dehydration or freezing.

2. The resin has extremely high purity. Close attention should be paid to the tightness of the product packaging to keep the packaging undamaged.

Avoid the resin from being polluted by air or other impurities, which will affect the performance of the resin.

3. The storage period of resin at room temperature is generally 12 to 24 months. Should adopt buy-and-use, buy-first, buy-first

The principle of use is to avoid storing ordinary resin for too long, which will affect the performance of the resin.

Storage of resin

1. The unused resin should keep the outer packaging bag intact to avoid its rupture and direct exposure of the resin to the air

In the air and stored in an environment of 0 ~ 40 °C.

2. Resin suspended in use should avoid the following situations:

①. The dehydration equipment should be filled with water. If the water must be drained, the equipment must be sealed to prevent resin water from dispersing.
